Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art obtained on the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
As shown in figure 1, the invention provides printed circuit board (Printed Circuit Board, PCB) formula power filter
Device includes：
Inductor 1, including an at least wire, wire are wrapped on inductor 1 and a pin are set at the port of wire
8.Inductor 1 is the element that electric energy can be converted into magnetic energy and stored.The structure of inductor 1 is similar to transformer, but
An only winding.Inductor 1 has certain inductance, and it only hinders the change of electric current.If inductor 1 leads in no electric current
In the state of crossing, it will attempt to hinder electric current to flow through it when circuit is connected；If inductor 1 is having electric current in the state of,
It will attempt to maintain electric current constant when circuit disconnects.Inductor 1 is also known as choke, reactor, dynamic reactor.Inductance is wire
When inside passing through alternating current, alternating flux, the magnetic flux of wire and the electric current for producing this magnetic flux are produced in the inner periphery of wire
The ratio between.When passing through DC current in inductance, the fixed magnetic line of force is only presented around it, not time to time change.
Circuit module, including：
Circuit board 3, it is upper that multiple connecting holes 7 are set.Pin 8 is by inserting connecting hole 7 so as to be connected with circuit board 3, this dress
The setting of middle increase connecting hole is put, plays a part of reducing welding procedure, makes production process simpler.
Electronic component 2, it is connected in a manner of plug-in unit with circuit board 3；Electronic component 2 is a capacitor and a resistor.Electric capacity
Usually filtration, such as electrochemical capacitor can may filter that high frequency with filtering low, ceramic condenser.Principle is exactly the logical friendship of electric capacity
Blocking characteristic, for electric capacity to AC signal path, signal frequency is higher, and impedance is smaller, and capacitance is bigger, and impedance is smaller, and right
Direct current signal open circuit.For example dc source both positive and negative polarity connects an electric capacity, believe for AC signal equivalent to short circuit, then fluctuation
Number it will be consumed by this electric capacity, then voltage is with regard to more stable, similarly, if digitally connecing an electric capacity, then ripple
Dynamic signal will flow into ground terminal, without flowing into next stage circuit by it and ground short circuit.Inductor 1 and electric capacity in this device
Device forms passive bidirectional network.Species, specification and the quantity of capacitor and resistor in wave filter can be come according to use demand
From not limiting herein.
Insulating base 4, fix a connection terminal 6 be used for realize and other electrical equipments connection, the connection terminal 6 passes through
Wear the insulating base 4 and insert the connecting hole 7 and be connected with the circuit board 3, the connection terminal 6 passes through the circuit board
3 are connected with the pin 8.A fixed support 5, the fixation for wave filter are also set up on insulating base 4.
As shown in Fig. 2 inexpensive pcb board formula power-supply filter also includes:
Housing 10, is bottom surface with insulating base 4, and housing forms the space of a closing with insulating base.Inductor 1 and electricity
Road module is placed in housing 9, plays buffer action, prevents the element in wave filter to be interfered.Housing is cylindrical structural, side
Just the use of wave filter.
A ground terminal 9 is also set up on insulating base 4, ground terminal 9 passes through connecting hole 7 and circuit through insulating base 4
Plate 3 connects.A ground terminal 9 is must be provided with power-supply filter to make power-supply filter can be with normal use.Such design
Reduce welding process so that production process is simpler, so as to reduce the use of labour so that wave filter is produced into
This reduction.
Housing 10 is plastic material, and laser printing label is used on the outer surface of housing 10.Reduction uses paper labels
Paper, so as to reduce labour cost, reduce production cost.
